Poultry Housing

objectives
• To know about need of housing for poultry
production
• Different types of poultry houses
• Location and layout of poultry houses
• Floor space requirement
• Different systems of rearing with relative
advantage and disadvantages.

DIFFERENT TYPES OF
POULTRY HOUSES
• Brooder/chick house
– It is used to brood and rear egg-type chicks from 0 to 8
weeks of age.
• Grower house
– It is used to grow egg-type birds from 9 to 18 weeks of
age.
• Brooder cum grower house
• Here, the birds are reared from 0 to 18 weeks of
age (entire brooding and growing period of egg-
type chicken)

• Layer house
– In which birds over 18 weeks of age are reared,
usually up to 72 weeks of age.
• Broiler house
– In which broilers (meat-type birds) are reared up to
6 weeks of age.

• Breeder house
– In which both male and female breeders are maintained
at appropriate sex ratio.
• Environmentally controlled (EC) house
– In which, entire environment is manipulated in such a
way that is optimum for the birds growth.

OPTIMAL ENVIRONMENTAL CONDITIONS FOR
REARING BROILERS
• Temperature - 22-300C (70-850F)
• Relative Humidity - 30-60 %
• Ammonia level - Less than 25 ppm
• Litter moisture - 15-25%
• Air flow - 10-30 metres/minute

Need for well designed poultry house
• Farm location, poultry house design and quality of farm
equipment will determine the operational efficiency,
performance of birds & bio-security
• Without proper housing, it is impossible to tap the full
genetic potential of the birds

Farm Location
• Farm must be located in a virgin place, where birds
are not reared earlier
• Purchase land with more east-west length
• Locate the farm at least 2 km away from residential
area & 5 km away from other poultry farms
• Purchase sufficient land, for future expansion

• Fence the entire area, to avoid
• Land must be elevated, with proper drainage
• Availability of water, electricity, labour & marketing
• Rear chicks & growers in different premises

– There should be a minimum distance of 50-100 feet
between chick and grower shed and the distance between
grower and layer sheds should be of minimum 100 metre.
– The egg store room, office room and the feed store room
should be located near entrance to minimize the
movement of people around the poultry sheds.
– The disposal pit and sick room should be constructed
only at the extreme end of the site.

Orientation
• constructed with their length facing E-W.
• To obviate direct sun light, draft and rain fall
into the building.

Correct orientation of tropical poultry houses parallel to
the shadow of a vertical pole,
during hot A.N.

–Layout should not allow visitors or
outside vehicles near the birds.
–The sheds should be so located that the
fresh air first passes through the
brooder shed, followed by grower and
layer sheds.
–This will prevent the spread of diseases
from layer houses to brooder house.

Open-sided houses
Very popular in our country.
Cheaper in construction and maintenance.
Plinth
Poultry houses are constructed in an elevated area
with a plinth of at least 0.60-0.90m in order to keep
the floor well above the ground to obviate seepage
of moisture from the surroundings.

Size
• Broiler – 1 sft and layer – 2 sft (Deep litter
system)
• Cage system layers 0.75 sft
• So the size of the house depends on the
number of birds to be reared.
Length
• The length of the house can be of any extent.
The number of birds reared and availability of
the land determines the length of poultry
house.

Width
•The open sided poultry houses in tropical countries
should have a width not more than 22 to 25 feet in order
to allow ample ventilation and aeration at the mid-
portion.
•Sheds wider than this will not provide adequate
ventilation during the hot weather.

•If the width of the shed is more than 25 feet, ridge
ventilation at the middle line of the roof top with proper
overhang is a must.
•Hot air and obnoxious gases which are lighter than air
move upward and escape through ridge ventilation.
•In environmentally controlled poultry houses, the width
of the house may be even 40 feet or more since the
ventilation is controlled with the help of exhaust fans.

Height
• The height of the sides from foundation to the
roof line should be 6 to 7 feet (eaves height)
and at the centre 10 to 12 feet.
• In case of cage houses, the height is decided
by the type of cage arrangements (3 tier or 4
tier).

Foundation
• Good foundation is essential to prevent
seepage of water into the poultry sheds.
• The foundation of the house should be of
concrete with 1 to 1.5 feet below the surface
and 1 to 1.5 feet above the ground level

Floor
•The floor should be made of concrete with rat
proof device and free from dampness.
•The floor of the house should be extended 1.5
feet outside the wall on all sides to prevent rat
and snake problems.
Doors
•The door must be open outside in case of deep-
litter poultry houses.
•The size of door is preferably 6 x 2.5 feet.
•At the entry, a foot bath should be constructed
to fill with a disinfectant.

Side walls
• The side wall should be of 1-1.5 feet height,
and generally at the level of bird’s back height.
• This side wall protects the bird during rainy
days or chill climate and also provides
sufficient ventilation. In case of cage houses,
no side wall is needed.

Roofs
 The roof must be draft and moisture proof.
 Insulation of roof helps in both summer and winter
 To reflect as much heat as possible, the roof should
painted with reflecting type of paint such as Al paint.

Roofs
• Asbestos or cement board roofs desirable for poultry roofs.
• Can be improved by adding insulation and painting or covering
with thatch.

Roofs
Metal roofs are good radiators unless insulated
not recommended as roofing materials.
Even with insulation , the outside of the roof
should be painted white to aid in keeping it cool.

• Different types of roofs are Shed, Gable, half-
monitor, full-monitor (Monitor), Flat concrete,
Gambrel, Gothic etc.
• Monitor type is mostly preferred in tropical
countries like India

Overhang
• The overhang of the roof should not be less than 3.5
feet in order to prevent the entry of rain water into the
shed.
Lighting
• Light should be provided at 7-8 feet above the ground
level and must be hanged from ceiling.
• If incandescent bulbs are used, the interval between
two bulbs is 10 feet. In case of fluorescent lights (tube
lights) the interval is 15 feet.

Cage layer fatigue
Fatty liver syndrome
Poor shell quality
Difficulty in manure disposal

Large tunnel ventilated broiler house, with exhaust
fans- to accommodate 50,000 broilers

ENVIRONMENTALLY CONTROLLED
HOUSING SYSTEM FOR BROILERS

Not much popular in india
Western countries b/c cold weather

House dimensions are usually 40-50 ft wide, 400-
600 ft long with 8 ft high sidewalls

Dropped Ceilings
To improve ventilation and reduce heating costs.
Dropped ceilings protect the trusses and ceiling insulation
by acting as a vapor barrier.
Modern houses are well insulated with false roofing to
reduce heat gain in the summer and heat loss in the winter.

Solid Side Walls
Most houses are constructed with solid side walls
rather than having open sides with curtains.

Heating
Broiler heating systems include radiant brooders, pancake
brooders, forced air furnaces and radiant tube heaters.

Heating
Hot air is lighter than cold air. This can result in
stratification with the air being warmer at the ceiling
than at the floor.
Circulation fans are often used to move hot air from
the ceiling down to the floor.

Ventilation
Ventilation delivers fresh air and removes excess
heat, moisture and undesirable gases from
the broiler house.
 A typical ventilation system in a EC consists of fans,
air inlets, evaporative cooling system and
controller/thermostats.
Houses are designed to deal with both cold and hot
weather extremes.

Cold Weather Ventilation
During cold weather, negative pressure ventilation is
used to provide fresh air, remove moisture and
minimize heat loss.
Fans exhaust air out of the house creating a slight
negative pressure inside the house.

Hot Weather Ventilation
During hot weather “tunnel ventilation” is used to keep birds
cool.
Tunnel ventilation systems consist of fans at one end of the
broiler house and large air inlets at the opposite end. The
fans pull air the length of the house at a velocity of 500 feet per
minute.
Tunnel ventilation removes heat from the building rapidly
and creates a wind chill that provides additional
cooling for the broilers.
